This part of IEC 62282 provides a set of specific rules, requirements and guidelines (i.e. so-called product category rules (PCR) according to ISO 14025 and thus in line with ISO 14040 and ISO 14044) for characterizing the environmental performance of stationary fuel cell combined heat and power (CHP) systems, and alternative systems for residential applications based on life cycle thinking primarily for communication to consumers. The environmental performance of a system is communicated to the consumer and the installer by means of an environmental product declaration (EPD).

This document covers stationary fuel cell CHP systems and alternative heat (and power) systems for residential applications that primarily serve heating purposes. The systems can be complemented with a hot water storage tank and one or more additional heat generators. The systems are connected to the electricity grid. The environmental performance is characterized in an EPD for each individual heat-related device or CHP generator separately. This document also describes how the environmental performance of a given combination of heat-related devices (including CHP generators) is characterized based on the environmental performance of its individual components. The domestic heat distribution system, district heating, or local infrastructures for fuel supply or for fuel storage are not considered.

This document focuses on residential applications, but can also be used to assess applications in the tertiary or service sector.

This document does not override, or in any way change, legally required environmental information, claims or labelling, or any other applicable legal requirements.
